Based on the rapid development of direct seeding rice in coastal area, 27 rice varieties contains Jigeng Series, Tiegeng Series, Beigeng Series and Yangeng Series, were used to analyze the seedling rate, salt tolerance and maturity of each variety under dry direct seeding condition. According to the field performance and yield to choose the suitable varieties for dry direct seeding in coastal areas. The results showed that Yangeng 933, Yangeng 1403, Yangeng 927, Yangeng 662, Yangeng 765, Yangeng 22, Fuyou 33, Beigeng 1604, Tiegeng 14 and Jigeng 88 had high seedling rate, strong salt tolerance and good maturity, the average yield was 8.03 t/hm2, which were suitable for planting as dry direct seeding rice in coastal areas.
Key words: coastal area; dry direct seeding; rice; adaptability
